ABSTRACT

Reconfigurable methods including areflective phase-shifter circuit are proposed based on complementary hybrid network power divider (PD). The analysis shows that this method can achieve continuously tunable power division ratio (PDR) and wide phase difference by changing the two horizontal transmission lines of the complementary hybrid network. In this way, areconfigurable PD based on acomplementary hybrid circuit-based reflective phase-shifter is designed to work at 2.45 GHz by replacing two horizontal transmission lines with 50 Ω reflective phase-shift circuits. The PDR of this fabricated reconfigurable PD is changed to the range of −29.12 to −0.24 dB, with the bias voltage being 0–8 V; meanwhile, the return loss and isolation are better than 23.2 dB.

摘要

提出了基于互补混合网络功率分配器（PD）的包括反射式移相器电路的可重构方法。分析表明，通过改变互补混合网络的两条水平传输线，该方法可以实现连续可调的功率分配比（PDR）和宽相位差。这样，基于互补的基于混合电路的反射式移相器的可配置PD通过将两条水平传输线替换为50反射反射式移相电路而设计为工作于2.45 GHz。这种制造的可重配置PD的PDR更改为-29.12至-0.24 dB的范围，偏置电压为0-8V。同时，回波损耗和隔离度优于23.2 dB。
